They will be widespread and unpredictable. By Dr. Nitish Priyadarshi An outbreak of the Ebola virus has killed 14 people in western Uganda last month. There is no treatment and no vaccine against Ebola, which is transmitted by close personal contact and, depending on the strain, kills up to 90 per cent of those who contract the virus. In recent years, Uganda has been hit with three Ebola outbreaks, the worst of which was in 2000, when more than half of the 425 people infected died. Cases of Japanese Encephalitis (JE) has gone up to 50 in the Assam State in Eastern India . The areas mostly affected by Japanese Encephalitis are Kamrup, Sivasagar, Dhubri, Morigaon, Darrang and Nalbari. More than 400 people in northern India have died last year from encephalitis, a rare condition that causes inflammation of the brain. Around 347 people have died in Uttar Pradesh, while 54 children have died in the neighbouring state of Bihar . Cases of malaria is increasing every...

The impact of global warming on agriculture is going to be worse. By Dr. Nitish Priyadarshi On the day you read this, the population of our planet will increase by 230,000 people. Hungry people. In 2012 about 140 million human beings will be born and some 55 million of us will die. That amounts to a net population gain of 85 million – more than 230,000 additional residents of the earth every day of the year. Many of these newcomers will suckle their meals from a mother’s breast for a year or so, but after that it will be up to Mother Earth to provide them food and drink. Our fragile, over extended planet and its hard working human population will have to feed those 230,000hungry people day after day for the next 66 years.   A growing global food shortage has caused prices to double in recent years, and a growing consensus of scientists now blames climate change as one factor in an equation that includes a burgeoning population and increasingly scarce water supplies. More people ar...

With special reference to Jharkhand State of India . By Dr. Nitish Priyadarshi. Palaeoclimatology, the study of climates during the geological past, is one of the most topical areas research in the geoscience at present. The threat of future climate change caused by higher levels of greenhouse gases, which would drastically alter many aspects of our environment, has prompted much research to try to understand how our complex climate system works. Only by understanding how climate has evolved over million of years can we identify important cycles with a frequency in excess of the short climate records we possess. These climate cycles have the potential to have a profound effect on our environment. The determination of past climate parameters by the use of paleohydrologic conditions is an important phase of paleoclimatology. The present climate of any local area, on any continent, and around any lake basin, depends on the same factors which controlled Pleistocene climate. The study of p...

It is definitely going to affect the productivity of the soil and agricultural growth. by Dr. Nitish Priyadarshi  Above photographs shows how the poisonous Parthenium grass is covering the agricultural lands in Gaya district of Bihar state in India . It is definitely going to affect the productivity of the soil and agricultural growth. Gaya is already under the water stress zone which affects the irrigation. Growth of these herbaceous plants   will increase the problem many fold. Lack of awareness among the local people and government agencies had helped these plants to grow rapidly on the vast areas of the district. It will not only affect the agricultural products but also the health of the local villagers with asthma, Allergic, Trinities Sinusitis, dermatitis (type of skin disease) especially among the childrens, Eczema, Allergic papules and all types of Allergic reactions. Parthenium weed's botanical name is Parthenium Hystrophorous . It is a herbaceous plant, and a na...

Heat waves are killing them. by Dr. Nitish Priyadarshi Below are the pictures of the dead bats taken by me. Yesterday it was very unfortunate day for me. I got the news that dozens of bats are dying in Morhabadi field in Ranchi city. When I visited the spot I saw dozens of bats killed and few were fighting with death in front of me. Immediate cause may be the heat waves coupled with some types of virus. As there is no shelter from the direct Sun rays these bats were direct affected with Sun's heat. In winter it was with crows and now it is the turn of bats. Ranchi has not witnessed constant high mercury for more than a fortnight. The mercury used to go up in past but it used to dip in four to five days time. Bats  are mammals  of the order  Chiroptera   whose forelimbs form webbed wings , making them the only mammals naturally capable of true and sustained flight . Bats are present throughout most of the world, performing vital ecological roles of  pollinating ...

My  book on   Understanding Different Environmental and Geological Issues From Past to Present. Product Details Paperback:  280 pages Publisher:  Bloggingbooks (April 20, 2012) Language:  English ISBN-10:  3841770339 ISBN-13:  978-3841770332 Product Dimensions:  8.7 x 5.9 x 0.6 inches Price: $64.00 Book Description Publication Date:  April 20, 2012 Our planet is at risk. The current explosion in the human population is forcing us to a simple but pivotal choice: stabilize the planet or perish. The coming years will bring grave crisis-environmental, economic, human. Only if we achieve a close understanding of the system of which we are part- how it came about and how it works- will the next generation be positioned to cope with the emerging problems. Geology and environment has a remarkable influence on our lives today, as it has on all life since the beginning billions of years ago. Perhaps the clearest influence we see of this is through the ...

Around  Ranchi  city typical structures are encountered on the rocks. by Dr. Nitish Priyadarshi Below are the pictures of the typical weathering structures on the Rocks of the Ranchi city. Weathering   is the breaking down of   rocks ,   soils   and   minerals   as well as artificial materials through contact with the Earth's atmosphere ,   biota   and waters. Weathering occurs   in situ , or "with no movement", and thus should not be confused with   erosion , which involves the movement of rocks and minerals by agents such as water, ice, snow, wind and gravity. Two important classifications of weathering processes exist – physical and chemical weathering. Mechanical or physical weathering involves the breakdown of rocks and soils through direct contact with atmospheric conditions, such as heat, water, ice and pressure. The second classification, chemical weathering, involves the direct effect of atmospheric chemicals or biolog...
